18 miles on a 48v 20ah battery?
That 53wh/mile.. That's horrific...
I get at WORST 30wh/mile and my bike with me on it weighs, over 350lbs..
Something is wrong.. Do you have a watt meter to test how many AHs you're getting?
I get 21 miles off of 36v 15ah.
FORGET volts.. .7v per cell at 2.8v unloaded goes FAST.
